Yes Dave, you would need the wiring loom from the donor engine as well and probably a new ECU to run it as well - I am no expert but you may be able to use the ECU from an STi or it would definitely work with an aftermarket ECU such as an Alcatek.

I would drop Bob Rawle a quick email and see what he advises.

are you thinking buy a complete sti engine drop it in my car remap then away to go or have it rebuilt first?

Dave Y

iTrader: (52)

There is a very nice white sti for sale putting all sorts of ideas in my head.

Cannon Fodder

iTrader: (100)

Well I was thinking that you'd buy the STi engine, have it built into a 2.1 and then dropped into your car.

TimH

iTrader: (11)

Newage STi engine - whether 2.0 or 2.1, or 2.5 for that matter - dropped in to newage WRX is quite common. AVCS wiring is easily done, but you will need either an STi ECU or aftermarket to get the AVCS solenoid drivers and the AVCS cam inputs.

Most common, and most cost effective, is to get an STi ECU and have that remapped, unless you're looking for 500bhp plus and/or "motorsport" features such as launch, ALS, flat foot shifting, multiple maps etc etc.

Happy to advise on wiring if needed

i will be having a chat with Ryan then make a decision as to which way i go.
I am still tempted by the white sti for sale.On the other hand i have done a lot of mods to my car and the 2.1 build would top it off nicely.

Dave Y

iTrader: (52)

Started the ball rolling today,Ryan is getting in touch with Alyn at
AS Performance to start the short block build.

Dave Y

So now i need to buy a turbo..........MDX321T
..........800cc injectors
..........Hybrid fmic
..........Fuel pump

and that is just for starters.All the above i want brand new.The search begins.

Hi Dave

From personal experience I would go with 2.1L,its awesome engine and with right turbo and heads will be awesome to drive

MDX321T on yours with 2.1L will be awesome and highly recommend this turbo,but still I would go on this turbo with better heads,WRX heads are OKish at this level,but when you are wanting to run 450bhp,get Spec C or JDM big port heads if its budget or UK STi heads should do nice job on yours

800cc injectors will be OK on yours,but after running reflowed injectors on ours I've hate them,du this if its budget ID 1000cc injectors I would choose

Hybrid FMIC is best have run,but for yours needs should be OK too Japspeed FMIC,have run this FMIC at 490bhp without the issue

Fuel pump,340LPH RCM or HRC should do job on yours without the issue and I'm sure Ryan or Alyn will advise you what will be best matey

Good luck with yours

Thanks,Jura

Dave Y

iTrader: (52)

Cheers Jura Bob Rawle suggested the 800cc injectors and said they should not be flow matched,he also advised the MDX.Hopefully it will be finished in time for Japfest at Castle Combe.

Dave Y

iTrader: (52)

Just bought the RCM 340 lph fuel pump from Advanced Automotive in Bristol.
So that is one item on long list i can tick off.

Dave Y

iTrader: (52)

Mr Rawle has suggested i go with an Alcatek ecu Parallel fuel lines and a Fpr .More expense!

jura11

iTrader: (7)

Hi Dave

I would trust Bob R and about the flow matched injectors,speak with Paul or Richard@Zen performance about their injectors

MDX 321T or MDX-555 450 shoudl do job on yours,although SC42 can be good alternative on yours,really depends on what and how much power you want to run and what fuel or if you are thinking to run meth on yours

Thanks,Jura
RCM Fuel pump are great and this pump should do job on yours,we are run 340LPH on 2.1L with 750cc injectors at 3bar fuel pressure and we are hit on 20% meth and 25HP NOS around 89% IDC(Injector Duty Cycle)

Thanks,Jura

I would go personally with Syvecs Dave,its worth the extra over AlcaTek,just speak with Ryan or above guys and they can confirm,if ECU then Syvecs is only ECU which I would put on my car,I wouldn't use on my car anything what is called SimTek or AlcaTek

Parallel lines and FPR yes this I would too suggest,speak with Ryan and I'm sure he will able to help you with this too Dave

Thanks,Jura

the new Alcatek is a very capable ECU mapped correctly albeit not in the same league as SYECS, but then not the same costs............

as for rails then we are now re-producing the Carl Davey Designs rails, etc. and fit & quality stands against the best on the market

Dave Y

iTrader: (52)

I will see how the budget is looking.

TimH

iTrader: (11)

Main benefit of Syvecs is the built-in logging which, as yet, AlcaTek doesn't offer. Other than that, it's a close call between the two for a road car IMHO.

Logging, via Toucan, for AlcaTek is not far off though...just need to get settled in to the new office next week, and crack on with the software

Dave Y

iTrader: (52)

I am looking for a reliable 450 ish.
Excuse my ignorance but will i need all this "logging"? Etc.
The car wont be seeing any trackdays

TimH

iTrader: (11)

Logging is useful to check everything's running OK...and mostly used if you do track days etc. If your's is a road car, it is more a "geek" thing as if it's mapped well you shouldn't see any issues, nor need to be checking it out.

But, to answer your question, logging allowa you to check fuelling, lambda (AFR) etc. You could do a "pull" and download the logs and make sure everything is as it should be.

Dave Y

iTrader: (52)

I was thinking AlcaTek if i have to upgrade ecu.
Do i have any other options without spending loads?

jura11

iTrader: (7)

Hi Tim

Would you swap on yours Syvecs for AlcaTek or SimTek?

Close call between the Syvecs and AlcaTek/SimTek I wouldn't say this

I wouldn't

Jura

Hi Dave

Looging is useful on road car or any other car if you can have this

Logging is good if you want to be sure on 100% everything is OK,if you are not 100% sure you don't need to visit yours mapper,in this case you will send him log to yours mapper and mapper will tell you what can be wrong or if its everything OK

Yours mapper can send you tweak map without the coming to mapper or mapper can send you the map with the tweaked parameters(enabled ALS,LC etc)

Price difference is not so high,if you take to account everything,if you want to have enabled ALS or LC then you pay extra for this on AlcaTek or SimTek,this is free on Syvecs,Logging is free on Syvecs,this is for extra on AlcaTek or SimTek

If you are running Race dash,the Syvecs is only option,Bluetooth modul for iPad/iPhone or Android is nice addition etc

If its worth extra,yes. Resale value of the AlcaTek is around £500-£700,Syvecs resale value is around £1200,fully fitted and mapped Syvecs is around £1600

Here are all features of all ECU

http://bbs.22b.com/forums/showthread...-options/page2

If its budget I would choose Syvecs,if not stick with OE ECU,Bob R still running on his car OE ECU at high 500bhp

Thanks,Jura

AS Performance

iTrader: (4)

a 'fully' mapped SYVECS will be far more than £1600 due to the complexity and options available to be utilised

TimH

iTrader: (11)

And a standard, mapped, Syvecs will be £1600 +VAT....so nearer £2k in reality.

For a ROAD car with NO track work, the AlcaTek is difficult to beat IMHO. For a track/drag car, or for cars where mods are made frequently, or for the nerds amongst us, the Syvecs is a great choice. If I didn't take mine on the track, and if it wasn't pushing the limits of a 2.5 SCDB block, I would be quite happy with an AlcaTek.

For the OP, I still think AlcaTek is a good choice *if* you decide to go after-market.

But you may well find OEM with EcuTek or open source suits you very well. I would trust your mapper's opinion on this as it's their reputation at stake!!

Dave Y

iTrader: (52)

So what are the limitations of my oem ecu that has already been mapped by Bob Rawle? I know it would need a remap but would the standard ecu fall short of my power estimate? Apologies if this is a daft question.

jura11

iTrader: (7)

Map tweak most of the mappers charging same for all aftermarket ECU

Fully mapped Syvecs etc I would expect £1800,setting/mapping Syvecs is not different from any other ECU,if mapper know as most to know how to map Syvecs,

You know alone Alyn depends on mods you have and if you want to have fitted Toucan,extra sensors etc,then off course price will go up like with any other ECU


Jura
Yes agree AlcaTek will cost you in region £1200,but for extra you have Syvecs ECU which does what you want and not just does the job

Syvecs I'm recommending only due this,just due we are run the Syvecs and simply is worth the money,plus after sale care from Syvecs you know alone is hard to beat

Agree best will be speaking with mapper,if mapper is comfortable to map OE ECU at 450bhp,then why OP needs to spend money for aftermarket ECU


Jura

OE ECU shouldn't be limiting factor at 400's bhp,limit is only at MAF,but you still can use bigger MAF tube or relocate MAF sensor to intercoler pipework(blown through MAF) and boost limit on OE ECU is around 1.4-1.6bar,but this dictate MAP sensor

I would speak with yours mapper about how he is comfortable to map OE ECU at this level and I would go with his decision

And I would to just add I'm not dealer for any above mentioned ECU

I spoke to Ryan earlier this wont be finished by May.Gutted to be honest.
I am in two minds to sell up. Its probably worth more in bits.I will have to have a good think about things over the weekend.

I Agree 100% Rome weren't built in a day you knowlook at all the biggest builds on here some of them have taken years to complete,just be patient mate it will be worth it in the end.SJ.

Dave Y

iTrader: (52)

the car is still on the road,i was hoping to get engine built then put my car off the road for 3/4 weeks job done.
i might have to break it to get a few quid back which is a pity because the bodywork is immaculate as is the interior.I am still undecided which way to go with this.
